13 TYPE TDE & TDEB (R22) INTRODUCTION TDE Range 3 7 1/2 TR TDEB Range 8 40 TR The TDE series of thermostatic expansion valves is designed for use in: Air conditioning systems Heat pumps Water chillers Refrigerated containers Traditional refrigeration systems The TDE product programs consist of two hermetic valve designs: Single port (type TDE) and balanced port (type TDEB).Valve selection is determined by the application and the capacity required. Single port version (type TDE) The single port s simplified construction is designed for use on systems with small capacities (3 to 7.5 TR R 22). Single port design is effective because in smaller capacities condensing pressure is negligible. Type TDE single port valves can also be used for bi-flow applications in the same capacity range. Balanced port versions (type TDEB) The balanced port design has been developed for large capacity systems (greater than 8 to 40 TR) where fluctuating condensing pressures are present. The balanced port feature eliminates any influence by condensing pressure on the expansion valve function in the normal flow direction. The TDEB design is unique in that it also provides a balance function in the reverse flow direction making it ideal for use in biflow applications. All TDE valves are available with a selection of bulb charges with or without maximum operating pressure (MOP) function. Single and industrial pack quantities are available. 183

16 TYPE TRE10, TRE20, TRE40, AND TRE80 INTRODUCTION TRE thermostatic expansion valves have been designed and developed for soldering into air-conditioning and refrigeration systems. Their hermetic tight design meets environmental demands for today and the future. They can be used in systems ranging in capacity from 8 to 70 TR (R 22). The TRE design incorporates a forged brass body with the entire power element, including the capillary tube and bulb, fabricated from stainless steel. The straight through bimetal solder connections are formed from deep drawn stainless steel and copper. The valve incorporates a 2-way balanced port orifice making it ideal for biflow operation. External superheat adjustment is a standard feature on all TRE valves. For non-adjustable OEM versions, a setting assembly is available for field retrofit. Contact Danfoss for further information. FEATURES Bimetal connections waterless soldering quicker installation times higher productivity Developed for R 410A R 22, R 134a, R 410A, R 507 and other fluorinated refrigerants Laser-welded power element longer diaphragm life high pressure tolerance and working pressure Stainless steel power element, capillary tube and bulb high corrosion resistance high strength and vibration resistance fast installation: self-aligning bulb secures with one strap good thermal contact and transmission Two-way balanced port/bi-flow function superheat unaffected by condensing pressure independent of flow direction one valve for heat pump service Stainless steel double contact bulb straightforward and fast installation good thermal contact and heat transfer Adjustable/non- adjustable version Setting spindle assembly can be retrofitted to non-adjustable version 186
